Description
Summary:Substantial effort is required to produce vehicular access ramps leading to subsurface ice cap facilities and to keep them from filling with drift snow. This report describes a technique for producing, maintaining and closing such ramps and outlines the procedure for covering the ramps, first to the surface and then, using a formed processed snow structure, above the surface. The results of a series of tests designed to evaluate various snows as construction materials indicate that snow disaggregated by the backcast Peter miller and subjected to immediate vibratory compaction is an excellent construction material. Application of the test results to a number of previously defined relationships for snow produced a method for designing formed processed snow structures. The method is illustrated by the design and construction of an above-surface access to an existing facility at Camp Century, Greenland. Performance of the access is discussed and documented by installed instrumentation. Construction of entire ice cap stations of formed processed snow is suggested. (Author)
